Shockey caught a 7-yard TD pass from Drew Brees late in the first quarter Sunday before he was hit hard by Carolina's Charles Godfrey. Shockey staggered to his feet and then walked to the locker room.
Just before halftime, Shockey was spotted walking from the locker room to the back of an ambulance while dressed in street clothes. There was no further word on his condition.
The milestone catch gave Shockey 33 touchdowns in his nine-year career.
